The NASA project NEOWISE, which has given astronomers a detailed view of near-Earth objects – some of which could strike the Earth – ended its mission and burned on reentering the atmosphere after ...

Jupiter, king of our solar system’s planets, continues to dominate the night sky in February. Lying inside the zodiac ...

The cast of exoplanets has an extraordinary new member. Using ESO’s telescopes, astronomers have discovered an approximately seven- Jupiter-mass companion to an object that is itself only twice as ...

A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may have significantly altered the orbits of the four outer planets in our ...

When a star is young, it is often still surrounded by a primordial rotating disk of gas and dust, from which planets can form. Astronomers like to find such disks because they might be able to catch ...

This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

The Orion Nebula (also known as M42) is one of the brightest nebulae in the night sky even visible to the naked eye; it appears as the middle “star” in the constellation Orion’s sword. This nebula is ...

Are they stars? Are they planets? Or are they neither? Some rogue planetary mass objects that wander the cosmos alone could be created when young star systems clash, meaning they represent an entire ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...
